SPECIFICATION forming part of Letters Patent No. 700,513, dated May 20,1902.

Application filed June 24, 190].-

seri al No 65,835. (No model.)

To all whom it mag congenial- Be it known that I, JURGEN PETER LANGE, acitizen of the United States, and a resident of Passaic, in the countyof Ifassaic and State of New Jersey, have inveii'tedfa new and ImprovedRoll, of which'thefollowing is a full, clear, and exact description. i

The invention relatesto wringing and other machines using rubber. rolls;and its object is to provide a new and improved roll arranged" to holdthe rubber faces against separate movement or stretching andto permit otcon veniently assembling the several parts constituting the roll. a V YThe invention consists of novel features and parts and combinations ofthe same, as will be fully described hereinafter and then pointed out inthe claim.; V

A practical embodiment of theinvention is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar charactersof reference indicate corresponding parts'in all theviews.

Figure 1 is a side elevation of the improvement with parts insectiomFig. 2 is a transverse section of the same on the line 2 2 of Fig. 1 andFig. 3is a somewhat-similar section, but taken on a line adjacent to oneof the heads. t

On theshaft Aare -keyed"or otherwise secured the hubs of"'se'ts.ofivwheels B, each set carrying a rubber ring-O on its peripheral face.Thewheels B and rings Ojare held against longitudinal movement on theshaft A by headsD, fastened together by longitudinal bolts E, extendingthroughthe open hubs of the wheels B aswill bereadily undestood byreference to the drawings,the bolts when screwing up the nuts thereonserving to draw the heads sufficiently tight against the outermostwheels and rings to securely clamp all of the parts together.

Each set of wheels B consists of two wheels made in sections fastenedtogether by bolts or other means, as is plainlyindicated in Figs. 2 and3, and each wheelis provided on its peripheral face with teeth B,preferably made V -shaped and somewhat inclined transversely, asisplainly indicated in Fig. 1, and the inner sides of the rings 0arecorrespondingly toothed or serrated to fit the teeth B of a set ofwheels to hold the rubber ringsC against movement independent of therota side's of a ring a short distancefromthe inside toward the'outside,asindicat'ed in'Fig. 11' Thus the outer portions of therubber rings (3are in firm contact witheach 'other and are completely unobstructed topermit the rings to possess the elasticity and flexibility necessary inthe machines for which the rolls arelintended.

It will'thus be observed that my device comprisesgin' efiect', a numberof semicircular sec' tions placed together edge to edge so as to formwheel members, endless bands of resil ient material encircling thesewheel members in such manner as to hold them together and also tohold-togetherthe oppositely-disposed semicircular sections in'each wheelmember; longitudinal rods running entirely through the roll, and shortboltssecuring together the semicircular sections of each of the Wheelmembers. Byithisarrangement the resilient bands coact with I theshortabolts in holding together. pairs of semicircular members and alsocoact with the long rods in holding the several wheel members togetheri-n'fa continuous cylinder.

Having thusfully described mydnyention, I claim as new and desire tosec'ure' by -Letters Patent Aaroll,- comprising semicircular 4 sectionsplaced'together edge to edgeso as to form wheel membe'rs, en dless bandsofresilient material encircling-saidwheel members in such manner as tosecure, aiplura'lity of said wheel members together and also to presstogether the semicircular sections in each wheel member, bolts disposedsubstantially at right angles to the axes of said wheel members forfurther securing together the semicircular sections of each wheelmember, and logitudinal rods passing through all of said-wheel membersparallel with the axes thereofiforthe purpose of clamping'said wheelin'eniberstogether. In testimony whereof I have signed my name to thisspecification in thepresenoe of two subscribing witnesses.
